Document management apparatus and recording medium

Abstract

A document management apparatus includes a reception unit, an operation information extraction unit, a memory, an executability determination unit, and an operation execution unit. The reception unit receives an operation request for an electronic document from an operator. The operation information extraction unit extracts operation information related to the operation request. The memory stores operation history information which is an accumulation of previous operation information which is operation information related to previous operation requests previously made for electronic documents. The executability determination unit reads the operation history information from the memory to determine whether or not an operation pertaining to the operation request is executable on the basis of the operation information and the operation history information. The operation execution unit executes the operation pertaining to the operation request in the case where the executability determination unit determines that the operation is executable.

What is claimed is:

 an operation execution unit configured to, in the case where the executability determination unit determines that the first operation is executable by determining that the first operation matches the second operation, execute the first operation pertaining to the operation request, wherein 
 the operation execution unit is further configured to, in a case where the executability determination unit determines that the extension of the electronic document, as indicated in the operation request, matches the extension of the electronic document, as indicated in the operation history information, execute the operation pertaining to the operation request. 
 
     
     
       2. The document management apparatus according to  claim 1 , further comprising:
 an operation history acquisition unit configured to integrate the operation information extracted by the operation information extraction unit into the operation history information as the previous operation information. 
 
     
     
       3. The document management apparatus according to  claim 1 ,
 wherein the operation information and the previous operation information include information indicating an operation content and information indicating the electronic document as an operation object, and 
 the executability determination unit is further configured to determine that the operation is executable in a case where the operation history information includes such previous operation information that the operation content in the operation information and the operation content in the previous operation information match each other and the operation object in the operation information and the operation object in the previous operation information match or are similar to each other. 
 
     
     
       4. The document management apparatus according to  claim 1 ,
 wherein the operation information and the previous operation information include information indicating an operator and information indicating an electronic document as an operation object, and 
 the executability determination unit determines that the operation is executable in a case where the operation history information includes such previous operation information that the operator in the operation information and the operator indicated in the previous operation information match each other and the operation object in the operation information and the operation object in the previous operation information match or are similar to each other. 
 
     
     
       5. The document management apparatus according to  claim 3 ,
 wherein the electronic document contains image information, and 
 the executability determination unit is further configured to extract the image information from each of the electronic documents as the operation object for the operation request and the electronic document as the operation object for the previous operation request to analyze the extracted image information, and to determine that the operation object in the operation information and the operation object in the previous operation information are similar to each other in the case where it is determined that the image information extracted from the electronic document as the operation object for the operation request and the image information extracted from the electronic document as the operation object for the previous operation request are similar to each other. 
 
     
     
       6. The document management apparatus according to  claim 5 ,
 wherein the image information includes a face image, and 
 the executability determination unit is further configured to determine that the operation object in the operation information and the operation object in the previous operation information are similar to each other in the case where it is determined that the face image included in the image information extracted from the electronic document as the operation object for the operation request and the face image included in the image information extracted from the electronic document as the operation object for the previous operation request are a face image of an identical person. 
 
     
     
       7. The document management apparatus according to  claim 3 ,
 wherein the electronic document contains audio information including a voice, and 
 the executability determination unit is further configured to extract the audio information from each of the electronic document as the operation object for the operation request and the electronic document as the operation object for the previous operation request to analyze the extracted audio information, and to determine that the operation object in the operation information and the operation object in the previous operation information are similar to each other in the case where it is determined that the voice included in the audio information extracted from the electronic document as the operation object for the operation request and the voice included in the audio information extracted from the electronic document as the operation object for the previous operation request are uttered by an identical person. 
 
     
     
       8. The document management apparatus according to  claim 1 ,
 wherein the operation information and the previous operation information include information indicating an operation time, and 
 the executability determination unit is further configured to extract from the operation history information the earliest operation time in a day and the latest operation time in a day among operation times in the previous operation information, and to determine that the operation is executable in the case where the operation time in the operation information falls between the earliest operation time and the latest operation time. 
 
     
     
       9. The document management apparatus according to  claim 1 ,
 wherein the operation information and the previous operation information include information indicating an IP address of a terminal utilized by an operator, and 
 the executability determination unit is further configured to determine that the operation is executable in the case where the operation history information includes such previous operation information that the IP address in the operation information and the IP address in the previous operation information match each other. 
 
     
     
       10. The document management apparatus according to  claim 1 ,
 wherein the operation information and the previous operation information include information indicating a client utilized by an operator, and 
 the executability determination unit is further configured to determine that the operation is executable in the case where the operation history information includes such previous operation information that the client in the operation information and the client in the previous operation information match each other.
